1.Derive an equation and solve for the volume V of a CSTR, operated isothermically for the second-order reaction 2R->P, where rR=-kC^2 R. Data are k=6.0 L/mol-s, CRin=0.005 mol/L, CRout=0.0005 mol/L, and Q=100 L/s.
2.A tank contains 3,500 cubic meters of water and has a total sodium chloride (NaCl) concentration of 1,520 mg/L. Clean water (it has no sodium chloride) is then added to fill the tank up to a final volume of 4,000 cubic meters. The final sodium chloride concentration in the tank is [x1]mg/L. Report answer to the nearest 10 mg/L.
